Somewhat related, every year my parent's friends come over and stay for a week, and they have a kid. This is has been going on for five or six years; the kid's 9 now, but he might as well be three years old. At 9 years old, he can't brush his own teeth, he still gets served much smaller portions of food, he can't take a damn shower by himself and he is so reliant on his parents (namely his mum) to do everything for him, and whines to them constantly when he wants something. And they are both completely oblivious to how underdeveloped (for lack of a better word) he is for his age.

This is what you're going to do: you're going to get some of those firecrackers you throw at the ground and explode. I'm not talking about those weak-ass kid's ones; I mean the ones that blow the hell up like regular fireworks when the slightest pressure is applied to them. Next, you're going to put these anywhere he might conceivably stand on, lay on, or sit down on, so that he'll constantly be startled by small explosions. Keep this up as long as you can, switching hiding spots randomly. Eventually, he'll only have two choices; either man up and become a badass, or get completely mentally broken, constantly in fear of the firecrackers. Either way, you win.

I was gonna make him play Ninja Gaiden while hanging off of something, as any place he would stand, sit, or lay on would have firecrackers. And then I would chuck one at him whenever he took damage in the game.
